The measurement of Cu, Fe, and Zn isotopes in natural samples may provide valuable information about biogeochemical processes in the environment. However, the widespread application of stable Cu, Fe, and Zn isotope chemistry to natural water systems remains limited by our ability to efficiently separate these trace elements from the greater concentrations of matrix elements.

The chemical form of iron is an important factor affecting the iron availability of vegetarian diets. Less than 40% of the iron in meat, poultry, and fish is in the heme form, which is more efficiently absorbed than the remaining nonheme iron present in these and all other foods (11– 15).Nonvegetarian diets with substantial amounts of red meat supply about 2 mg/d, or 10–12%, of the total ...

Supplementing iron and zinc: double blind, randomized ...

Results: Iron supplementation alone increased diarrhea, but adding zinc, separately or together, attenuated these harmful effects. Combined zinc and iron was as effective as iron alone for iron outcomes. All supplements were vomited <1% of the time, but combined iron and zinc were vomited significantly more than any of the other supplements.

Ion Separation

 · Chemical Separation by Precipitation. A mixture of metal ions in a solution can be separated by precipitation with anions such as Cl −, Br −, SO 4 2 −, CO 3 2 −, S 2 −, Cr 2 O 4 2 −, PO 4 2 −, OH − etc. When a metal ion or a group of metal ions form insoluble salts with a particular anion, they can be separated from others by ...

 · This paper focuses on the selective leaching of zinc from high iron-bearing zinc calcines. The FactSage 6.2 program was used for the thermodynamic analysis of the selective reduction and leaching, and the samples reduced by carbon and carbon monoxide were subjected to acid leaching for the separation of zinc from iron. It is shown that the generation of ferrous oxide should be avoided by ...

Amalgam (chemistry)

Important amalgams Zinc amalgam. Zinc amalgam finds use in organic synthesis (e.g., for the Clemmensen reduction). It is the reducing agent in the Jones reductor, used in analytical chemistry.Formerly the zinc plates of dry batteries were amalgamated with a small amount of mercury to prevent deterioration in storage. It is a binary solution (liquid-solid) of mercury and zinc.

Extraction and separation of zinc, lead, silver, and ...

Except for the main metal, zinc, other metals in the solution have relatively low concentrations, so the recovery of zinc is a prime consideration. The solvent extraction method has been explored by researchers for extracting zinc from spent solutions and was shown to have a good separation effect (Sinha et al., 2016).
